Antistatic nano self-cleaning coating for glass and antistatic nano self-cleaning glass prepared therefrom

Abstract

The invention relates to a self-cleansing coating, in particular to a nanometer antistatic self-cleansing coating for glass and nanometer self-cleansing glass prepared from the nanometer antistatic self-cleansing coating for the glass, and belongs to the technical field of functional film manufacturing. A preparation method of the nanometer antistatic self-cleansing coating for the glass includes the steps of (1), preparing a nanometer titanium dioxide crystal sol water solution, namely mixing titanium dioxide sol with water to form titanium dioxide gel, subjecting the titanium dioxide gel to hydrothermal synthesis to obtain nanometer titanium dioxide crystal gel, and dispersing titanium dioxide crystals into the water so as to form the nanometer titanium dioxide crystal sol water solution; (2), preparing an ATO nanometer crystal sol water solution; (3), mixing the nanometer titanium dioxide crystal sol water solution with silicon dioxide sol prior to ultrasonic dispersion, and regulating a pH value of the system to 6-10 with an alkaline solution so as to obtain a self-cleansing coating precursor; (4), mixing the ATO nanometer crystal sol water solution with the self-cleansing coating precursor prior to ultrasonic dispersion, and stirring sufficiently to obtain the nanometer antistatic self-cleansing coating.

Description

technical field [0001] The invention relates to a self-cleaning coating, in particular to an antistatic nano self-cleaning coating for glass and an antistatic nano self-cleaning glass prepared therefor, belonging to the technical field of functional film manufacturing. Background technique [0002] Hydrophilic self-cleaning glass is a kind of functional glass. Under the condition of water flow, the contact angle between water and glass is less than 10°, and the glass is tiled on the water surface to form a hydrophilic film. The water flow is removed to achieve the effect of glass self-cleaning. [0003] The preparation of hydrophilic self-cleaning glass is mainly divided into two types. One is self-cleaning treatment on the surface of the original glass sheet, and a protective film is attached to the self-cleaning surface. Later, the original glass sheet is laminated and hollowed out to form a finished glass. The advantages of this method The glass surface is easy to clean,...

[0003] The preparation of hydrophilic self-cleaning glass is mainly divided into two types. One is self-cleaning treatment on the surface of the original glass sheet, and a protective film is attached to the self-cleaning surface. Later, the original glass sheet is laminated and hollowed out to form a finished glass. The advantages of this method The glass surface is easy to clean, but the disadvantage is that it needs film surface protection in the process of meeting the finished product, and it is difficult to self-clean the LOW-E glass; the other is to coat the self-cleaning glass on the surface of the finished glass. This method is mainly The advantage is to solve the problem of difficult self-cleaning of LOW-E glass. The disadvantage is that the glass surface is easily polluted during the production process, and it is difficult to clean the glass surface during the self-cleaning process.
